Vroom's Expectancy and Other Motivation Theories Explained

Updated 10 October 2026 · Fact-checked

These are four process and need theories of motivation. Vroom says effort depends on expectancy, instrumentality and valence. Adams says people compare their input-output ratio with others. McClelland says achievement, power and affiliation needs drive behaviour. Alderfer groups needs into existence, relatedness and growth. Match the clue in the question to the theorist.

Understand Vroom's Expectancy and Other Motivation Theories

Motivation is the inner drive that makes people put in effort to reach a goal. Managers study it to understand why two employees with the same pay and job work with very different energy. Some theories list the needs people have. Others explain the thinking process by which people decide how hard to work.

Vroom's expectancy theory is a process theory. Victor Vroom said a person is motivated when they believe three things. First, effort will lead to good performance (expectancy). Second, good performance will lead to a reward (instrumentality). Third, the reward is something they value (valence). If any one of the three is zero, motivation falls to zero. Example: a sales executive at a Pune firm may doubt the target is achievable, or doubt the bonus will really be paid, or not care for the reward on offer.

Adams' equity theory says people compare their own ratio of outcomes (pay, recognition) to inputs (effort, skill, time) with the same ratio of a reference person. If the ratios are equal, they feel fairly treated. If not, they feel tension and try to restore balance. They may reduce effort, ask for more pay, change the comparison person, or leave. Over-reward can also cause discomfort, though underpayment is the more common problem.

McClelland's theory says needs are learned from life experience and shape behaviour. The need for achievement is the wish to do better, take moderate risks and get feedback. The need for power is the wish to influence or control others. The need for affiliation is the wish for friendly, close relationships. Alderfer's ERG theory compresses Maslow's five levels into three: Existence (physical and safety needs), Relatedness (social and esteem from others) and Growth (self-esteem and self-fulfilment). Unlike Maslow, several needs can be active together, and if a higher need is blocked the person may fall back to a lower one (frustration-regression).

Key formulas to remember

Vroom's motivation force
Motivation (Force) = Expectancy × Instrumentality × Valence
It is a product, so if any one factor is zero, motivation is zero.
Adams' equity condition
Own outcomes ÷ Own inputs = Other's outcomes ÷ Other's inputs
Equal ratios mean equity. Unequal ratios mean inequity, either under-reward or over-reward.
McClelland's three needs
nAch (achievement), nPow (power), nAff (affiliation)
High achievers prefer moderate risk, personal responsibility and feedback.
Alderfer's ERG
E = Existence, R = Relatedness, G = Growth
Existence ≈ Maslow's physiological and safety; Relatedness ≈ social and external esteem; Growth ≈ internal esteem and self-actualisation.

How to solve Vroom's Expectancy and Other Motivation Theories questions

Most questions test who said what, or ask you to match a situation to a theory. Use the same routine each time.

  1. 1Read the question and underline the clue words, such as effort-performance link, fairness, comparison, achievement, power or regression.
  2. 2Decide whether the clue points to a process (how people decide) or a content (what people need) theory.
  3. 3Match the clue: probability or reward value means Vroom; comparison with others means Adams; need to excel, control or belong means McClelland; three needs or falling back means Alderfer.
  4. 4For Vroom, name the missing element: expectancy, instrumentality or valence.
  5. 5For Adams, write the two ratios and check if they are equal.
  6. 6Eliminate options that belong to another theory, such as Maslow's five levels or Herzberg's hygiene factors.
  7. 7Pick the option that fits every part of the statement.

Quickest way: Clue-word matching

When to use it: Use for one-line MCQs where you must identify the theory, theorist or element.

  1. Fairness, comparison, ratio, referent: Adams.
  2. Effort, performance, reward, valence, expectancy: Vroom.
  3. Achievement, power, affiliation: McClelland.
  4. Existence, relatedness, growth, regression: Alderfer.
  5. If options mix theories, drop any that do not use the clue word.

Common mistakes in Vroom's Expectancy and Other Motivation Theories

  • Saying Vroom's theory lists human needs.

    Students group all motivation theories as need theories like Maslow.

    Fix: Remember Vroom is about expectation and choice. It has no list of needs, only expectancy, instrumentality and valence.

  • Mixing up expectancy and instrumentality.

    Both sound like beliefs about outcomes.

    Fix: Expectancy is effort leading to performance. Instrumentality is performance leading to reward.

  • Thinking equity means equal pay for everyone.

    The word sounds like equality.

    Fix: Equity compares ratios of outcomes to inputs. Two people may be paid differently and still feel fairly treated.

  • Treating McClelland's needs as inborn and in a fixed order.

    Students carry over the Maslow hierarchy idea.

    Fix: McClelland said needs are learned and have no fixed order. Different people have different dominant needs.

  • Saying ERG has five levels or moves only upward.

    Confusion with Maslow.

    Fix: ERG has three categories. Movement can be up or down, and more than one need can work together.

Worked examples

Example 1

Ravi, an employee at a Chennai firm, believes that working harder will improve his sales. He is also sure good sales earn a bonus. But he does not value the bonus, which is a small gift voucher. Which element of Vroom's theory is weak, and what is the likely motivation?
(a) Expectancy, high motivation
(b) Instrumentality, low motivation
(c) Valence, low motivation
(d) Equity, high motivation

Show the solution
  1. Effort leads to better sales: expectancy is high.
  2. Good sales lead to a bonus: instrumentality is high.
  3. He does not value the voucher: valence is low.
  4. Motivation = Expectancy × Instrumentality × Valence, so a very low valence makes the product low.
  5. Option (d) names equity, which is not a Vroom element.

Answer: (c) Valence, low motivation

Example 2

Asha and Meera do similar jobs in the same company. Asha puts in inputs of 10 units and gets outcomes of 20 units. Meera puts in inputs of 8 units and gets outcomes of 20 units. According to Adams' equity theory, how does Asha feel when she compares herself with Meera?
(a) Treated equitably
(b) Over-rewarded
(c) Under-rewarded
(d) Motivated by achievement need

Show the solution
  1. Asha's ratio = 20 ÷ 10 = 2.
  2. Meera's ratio = 20 ÷ 8 = 2.5.
  3. Asha's ratio is lower than Meera's, so the ratios are unequal.
  4. Lower own ratio than the comparison person means Asha perceives inequity of under-reward.
  5. She may reduce effort, ask for more pay or change her comparison person.

Answer: (c) Under-rewarded

Exam tips

  • Learn one clue word per theory. Most MCQs give that clue directly.
  • For Vroom, remember the three elements and that they multiply. A zero in any one gives zero motivation.
  • For Alderfer, expect a question on how it differs from Maslow: three levels, simultaneous needs, and frustration-regression.
  • For McClelland, link high achievers with moderate risk and feedback, and power with influencing others.
  • Do not spend more than a minute per question. With no negative marking, attempt every item.

Vroom's Expectancy and Other Motivation Theories: frequently asked questions

What is Vroom's expectancy theory in simple words?

It says you work hard when you believe effort will give performance, performance will give a reward, and you want that reward. These three beliefs are expectancy, instrumentality and valence. They multiply, so one zero kills motivation.

What is the difference between ERG theory and Maslow's hierarchy?

Maslow has five levels and people move up one step at a time. Alderfer has three categories: existence, relatedness and growth. In ERG, more than one need can be active at once, and a person blocked at a higher level can return to a lower one.

What are McClelland's three needs?

They are the need for achievement, power and affiliation. Achievement is the drive to excel. Power is the wish to influence others. Affiliation is the wish for warm relationships. McClelland said these needs are learned.

How does Adams' equity theory explain motivation?

People compare their outcome-to-input ratio with someone else's. If the ratios match, they feel fair and stay motivated. If not, they feel tension and may cut effort, seek a raise or leave.
